背景技术Background technique
为了应对未来垂直行业的需求,提出了私网的概念,即垂直行业的私有网络,专门用于服务垂直行业的用户。私网存在两种架构,一种是独立组网(Standalone),一种是非独立组网(non-standalone)。Standalone与公网架构是相互独立的网络,有自己独立的网元功能,non-standalone与公网架构是相同的。In order to meet the needs of vertical industries in the future, the concept of private networks is proposed, that is, private networks in vertical industries, dedicated to serving users in vertical industries. There are two architectures for private networks, one is independent networking (Standalone), and the other is non-standalone networking (non-standalone). Standalone and public network architectures are independent networks with their own independent network element functions. Non-standalone and public network architectures are the same.
针对standalone和non-standalone的非公共网络(non-public network,NPN),都需要支持封闭接入组(Closed Access Group,CAG)的操作,即需要让非NPN的用户不能够接入到该NPN网络,与此同时,可以让NPN用户可以接入到相应的网络得到相应的服务。For standalone and non-standalone non-public networks (non-public network, NPN), it is necessary to support closed access group (Closed Access Group, CAG) operations, that is, non-NPN users must not be able to access the NPN The network, at the same time, allows NPN users to access the corresponding network and get the corresponding service.
针对non-standalone的NPN的网络,可以采用网络切片的方式进行满足,即每一个NPN的网络都对应一个网络切片,但是目前网络切片的方式不能够满足CAG的需求,即不能让非NPN的用户禁止接入这个网络。For non-standalone NPN networks, network slicing can be used to meet the requirements, that is, each NPN network corresponds to a network slice, but the current network slicing method cannot meet the needs of CAG, that is, it cannot allow non-NPN users Access to this network is prohibited.

应理解,该通信系统中的接入网设备可以是任意一种具有无线收发功能的设备。该接入网设备包括但不限于:演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(baseband Unit,BBU),无线保真(wireless fidelity,WiFi)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等,还可以为5G,如,NR,系统中的gNB,或,传输点(TRP或TP),5G系统中的基站的一个或一组(包括多个天线面板)天线面板,或者,还可以为构成gNB或传输点的网络节点,如基带单元(BBU),或,分布式单元(distributed unit,DU)等。It should be understood that the access network device in the communication system may be any device with a wireless transceiver function. The access network equipment includes but is not limited to: evolved Node B (eNB), radio network controller (RNC), node B (Node B, NB), base station controller (base station controller) , BSC), base transceiver station (base transceiver station, BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), baseband unit (BBU), wireless fidelity (wireless fidelity, WiFi) The access point (AP), wireless relay node, wireless backhaul node, transmission point (TP) or transmission and reception point (TRP) in the system can also be 5G, For example, NR, gNB in the system, or transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of the base station in the 5G system, or it can also be a gNB or transmission point. Network nodes, such as baseband unit (BBU), or distributed unit (DU), etc.
在一些部署中,gNB可以包括集中式单元(centralized unit,CU)和DU。gNB还可以包括射频单元(radio unit,RU)。CU实现gNB的部分功能,DU实现gNB的部分功能,比如,CU实现无线资源控制(radio resource control,RRC),分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能,DU实现无线链路控制(radio link control,RLC)、媒体接入控制(media access control,MAC)和物理(physical,PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息,或者,由PHY层的信息转变而来,因而,在这种架构下,高层信令,如RRC层信令,也可以认为是由DU发送的,或者,由DU+CU发送的。可以理解的是,网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外,CU可以划分为接入网(radio access network,RAN)中的网络设备,也可以将CU划分为核心网(core network,CN)中的接入网设备,本申 请对此不做限定。In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB may also include a radio unit (RU). CU implements some functions of gNB, DU implements some functions of gNB, for example, CU implements radio resource control (Radio Resource Control, RRC), Packet Data Convergence Protocol (PDCP) layer functions, DU implements wireless link The functions of radio link control (RLC), media access control (MAC) and physical (PHY) layers. Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, under this architecture, high-level signaling, such as RRC layer signaling, can also be considered to be sent by DU , Or, sent by DU+CU. It can be understood that the network device may be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into network equipment in the access network (radio access network, RAN), or CU can be divided into the access network equipment in the core network (core network, CN), which is not limited by this application.
另外,在本发明实施例中,接入网设备为小区提供服务,终端设备通过该小区使用的传输资源(例如,频域资源,或者说,频谱资源)与接入网设备进行通信,该小区可以是接入网设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(small cell)对应的基站,这里的小小区可以包括:城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。In addition, in the embodiment of the present invention, the access network equipment provides services for the cell, and the terminal equipment communicates with the access network equipment through the transmission resources (for example, frequency domain resources, or spectrum resources) used by the cell. It can be a cell corresponding to an access network device (such as a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cell here can include: metro cell, micro cell ( Micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-rate data transmission services.
此外,LTE系统或5G系统中的载波上可以同时有多个小区同频工作,在某些特殊场景下,也可以认为上述载波与小区的概念等同。例如在载波聚合(carrier aggregation,CA)场景下,当为UE配置辅载波时,会同时携带辅载波的载波索引和工作在该辅载波的辅小区的小区标识(cell indentification,Cell ID),在这种情况下,可以认为载波与小区的概念等同,比如UE接入一个载波和接入一个小区是等同的。In addition, the carrier in the LTE system or the 5G system can have multiple cells working at the same frequency at the same time. In some special scenarios, the concept of the above-mentioned carrier and the cell can also be considered equivalent. For example, in a carrier aggregation (CA) scenario, when a secondary carrier is configured for a UE, the carrier index of the secondary carrier and the cell identification (Cell ID) of the secondary cell working on the secondary carrier will be carried at the same time. In this case, the concept of carrier and cell can be considered to be equivalent. For example, the UE accessing a carrier is equivalent to accessing a cell.
核心网设备可以与多个接入网设备连接,用于控制接入网设备,并且,可以将从网络侧(例如,互联网)接收到的数据分发至接入网设备。The core network device can be connected to multiple access network devices to control the access network device, and can distribute data received from the network side (for example, the Internet) to the access network device.
其中,以上列举的终端设备、接入网设备和核心网设备的功能和具体实现方式仅为示例性说明,本发明并未限定于此。Among them, the functions and specific implementations of the terminal devices, access network devices, and core network devices listed above are only exemplary descriptions, and the present invention is not limited thereto.
